Hi,all; this trans since Ive owned the van has always had a slow leak. Not too bad over time to top up, but now when climbing a hill it feels like something is under the acel pedal. I can manually shift it down and back but the pedal still keeps the rpms low so barley climbs, Im stumped. also when I really stomp on the accel it will slip into neutral maybe to protect er something? hmm..
